Seatalk1 to NMEA0183 with Arduino

[olewsaa]

Cool, it just show the benfit of more eyes and working together, it's often just a question of using the right search string.

I installed the library in question, but it fails to build even its own examples. This is sometimes a sign the building environment is incompatable, 
I use the Arduino IDE 1.8.12 which is fairly new. The errors are related to parameters in the function calling to some basic functions in 
the Arduino IDE framework. 

However, we are one the right track. The next challenge is to get the examples to build.
